Secure SDLC practices directly require input validation and bounds checking that prevent improper array indexing.

finds

Security testing in development can detect out-of-bounds array access but does not prevent the weakness by itself.

prevents

Secure development lifecycle mandates input validation and bounds checking that directly prevents improper array indexing.

prevents

Application security requirements include validation of untrusted input used for indexing or addressing memory structures.

prevents

Secure architecture principles encourage defensive coding patterns that reduce index-related vulnerabilities.

prevents

Secure coding standards explicitly require bounds checking and validation of array indices derived from untrusted data.
